1.5 -7V Input, 3 Amp, Ultra Low Dropout Regulator

Recommended alternative parts

  • TPS50601-SP  - The device has SIMILAR FUNCTIONALITY but is not functionally equivalent to the compared device.   Higher current, higher efficiency
  • TPS7A4501-SP  - The device has SIMILAR FUNCTIONALITY but is not functionally equivalent to the compared device.   Wider input voltage range support


The TPS7H1x01 is a low dropout (LDO) linear regulator that uses a PMOS pass element configuration. It operates under wide range of input voltage, from 1.5 V to 7V while offering excellent PSRR. The TPS7H1x01 features a precise and programmable fold back current limit implementation with a very wide adjustment range. To support complex power requirements of FPGAs, DSPs, or Microcontrollers the TPS7H1x01 provides enable on/off functionality, programmable SoftStart, current sharing capability, and a PowerGood open drain output. The TPS7H1x01 is available in a thermally enhanced16-pin ceramic flatpack package (CFP) and KGD (Bare Die) package.
